### Description 1) Added Sequence And Maps convenience APIs to create input Sequences and Maps and also visit the outputs. 2) Address OrtValue design issue when the values are created on top of the managed memory and the ortValues are used for sequence and maps creation. We should retain the original managed instances that keep the memory pinned. We opt to keep track of those and dispose of them within an instance of OrtValue that represents a Map or a Sequence. 3) Set `LangVersion` to default per [MS Versioning Docs.](https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/configure-language-version) ### Motivation and Context 1) When writing code examples, use of Map and Sequences API proved to be cumbersome. 2) It is a BUG, that we should address, as the managed memory can move by the GC and lead to intermittent crashes. 3) Make use of the most feature of the C#. |

ONNX Runtime is a cross-platform inference and training machine-learning accelerator.
ONNX Runtime inference can enable faster customer experiences and lower costs, supporting models from deep learning frameworks such as PyTorch and TensorFlow/Keras as well as classical machine learning libraries such as scikit-learn, LightGBM, XGBoost, etc. ONNX Runtime is compatible with different hardware, drivers, and operating systems, and provides optimal performance by leveraging hardware accelerators where applicable alongside graph optimizations and transforms.
